What brand of chuck do you have? I think the 1/4” refers to the length of the tenon. The diameter of the tenon should be about half the size of the chucks max/min opening range. Also, I find it helpful to use the tail stock center to help hold the piece I am turning for as much turning as possible.

I find that turning the tenon so that it has a slight flair, to match the inside of the chuck jaws, also helps hold the work piece more securely. My chuck doesn’t hold long pieces very well. That’s why I use the tail stock to do most of the turning and then back the tail stock out to finish up and sand.

Another thing that helps me is to make sure the tenon is not long enough to bottom out on the inside of the chuck. I think you get more support by having the work piece “sit” on the top of the jaws- just my opinion.
